Patent GB-329267-A (GB)
Title: A process and apparatus for purifying the exhaust gases of internal-combustion engines
IPC: F01N3/021
Filed: 1928-12-08
Abstract: 329,267. Markels, L. Dec. 8, 1928. Exhaust, dealing with. - Exhaust gases are purified by passing through a container A filled with a loosely confined mass of activated charcoal, e.g. nut shells carbonized at high temperature and activated by treating with air or steam at a lower temperature. The charcoal is confined between two separators c, c<1> each comprising a number of screens with intermediate filtering material, the separators bearing against shoulders c formed on the inlet a and outlet a<1> in order to provide an expansion chamber d and an outlet chamber d<1> for the exhaust gases. The container A is enclosed in a casing G, and is coupled either directly to the exhaust pipe or to a silencer F through a three way valve E, whereby the gases may be passed either through the purifier or direct to the atmosphere. The valve E may be provided with a spring-loaded relief valve, which opens should the flow of the gases be impeded

Title: Draft linkage for power-propelled scrapers
IPC: E02F3/64
Filed: 1946-12-10
Abstract: 619,445. Earth scrapers. LETOURNEAU, Inc., R. G. Dec. 10, 1946, No. 36474. Convention date, Jan. 22. [Class 68 (i)] In bowl - type earth - scrapers which are dragged forward by a yoke attached either to a two-wheeled tractor or to a towed wheeled carriage, the downwardly directed arms 25 of - the yoke 28 are connected to the sides of the bowl 21 by pivoted links 26. Normally, the weight of the bowl maintains these links in a downwardly directed position, but when the draw-bar load exceeds a certain value, which is liable to stall the tractor engine, then the links move towards a horizontal position. This movement allows the yoke to rise vertically and, since the means connected between the yoke and the front of the bowl for raising and lowering the bowl remains of a constant length during this movement, the front of the bowl is lifted up from the digging position. Stops 15a are provided for limiting the downward inclination of the links 25 when the draw-bar load is normal.

Filed: 1956-11-30
Abstract: 802,558. Mercury switches. VAPOR HEATING CORPORATION. Nov. 30, 1956 [Dec. 7, 1955], No. 36720/56. Class 38 (5). [Also in Group XXXVIII] An assembly for indicating the temperature of a circulating liquid, e.g. the cooling liquid of an I.C. engine, comprises a hollow body with a thin metallic well secured thereto for insertion in the liquid, a contact thermometer of the mercury column type being positioned in the well by means of a cushion and a sleeve surrounding the thermometer and clamped against the cushion by the securing of an electrically energizable relay to the hollow body. The latter 10 is threaded at 15 for insertion in a conduit 16 with the well 21 immersed in the liquid. The thermometer 24 has a bead 27 held between two washers 28, 29, forming the cushion, by an insulating sleeve 30, the upper end of which abuts the base-plate 12 of an electromagnetic relay 13. The coil 42 of the latter is normally energized so that its contacts normally complete the circuit of a normal-temperature indicator. If the liquid temperature reaches a certain value, contacts 36, 37 of the thermometer are bridged by the mercury to short circuit the coil 42, so that the relay contacts change over to energize an abnormal-temperature indicator.

Title: Apparatus for sensing perforated records
IPC: G06K7/08
Filed: 1954-12-20
Abstract: 761,219. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES COR. PORATION. Dec. 20, 1954 [Dec. 30, 1953], No. 36726/54. Class 106 (1). Perforated records are sensed by means of a pick-off coil on a magnetic core the flux in which is produced by a permanent or electromagnet and varied as the card perforations pass over a gap in the magnetic circuit. As shown, Fig. 1, a punched record card 13 is traversed over iron cores 12, an iron-wire brush 11 forming a pole-piece of a permanent or electromagnet 10 being provided for each core, and moving closer to its respective core as a hole is sensed to produce two voltage pulses of opposite polarity in a pick-off coil 14. The negative one of these pulses is selected by a rectifier 16, Fig. 4, lengthened by the R.C. combination 18, 17 and blocks a normallyconducting triode 20, the resultant positive anode pulse from which fires a thyratron 21 connected to a device 22. In a modification, Fig. 2, each iron wire brush 28 is disposed above the air-gap between pole-pieces 25, 26 of a magnet 24 and varies the reluctance of the associated magnetic circuit as a hole is sensed. In a further modification, Fig. 3 (not shown), the wire brush of Fig. 2 is dispensed with and the variation in reluctance of the various magnetic circuits produced by using perforated record cards having a magnetic backing so that the air-gaps of the magnetic circuits are short-circuited except when a hole is sensed. The pole-pieces 24, 25 may be moulded in a phenolic guide-plate 27.

In a machine tool a device for compensating for variations in dimensions of the cutting tools e.g. due to sharpening, comprises means for supporting a master tool or a particular tool to be used, 32, at a point remote from the point at which the cutting tool is to be used, gauge and sensing means 70, 72, 94, 96 for determining and providing a signal indicative of the diameter of the tool, adjustable stop means 102, 104 for determining the extent of movement of a tool head 28, 36 in the machine tool, sensing means 118, 120 for sensing and providing a signal indicative of the position of the stop means, and control means 128, 134 arranged to compare the two signals and to control actuating means 106, 108 which adjust the stop means accordingly. In a milling machine in which two opposed convex surfaces 38, 40 are to be milled in a workpiece 26, a tool 32 carried by a drive head 28 and by a supporting, head 36 is shifted linearly to mill the two surfaces, the depth of cut in each case being controlled by the position of the stop wedges 102, 104. The machine and compensating device are set up in the first place with a master tool 32 (or tool of identical dimensions to that to be used in the machine tool) in the compensation device and the stop wedges 102, 104 adjusted to give the required depth of cut and the control circuit adjusted to a balanced condition. Thereafter, if a different or resharpened tool is to be used it is first placed in the compensation device and the resultant signals from transducers 94, 96 used to reset the stop wedges 102, 104. Thus when the new tool is inserted and used in the machining process, the depth of cut is held at the same value. Stop wedges 102, 104 are locked in adjusted position by fluid pressure cylinder means 110, 112.

Title: Improvements in or relating to a method and apparatus for use in evaporator and/or distillation system
IPC: B01D3/14
Filed: 1954-12-30
Abstract: <PICT:0797045/III/1> In a process for the distillation of liquids, the overhead vapour is divided into two streams, one of which is condensed, the condensate is pumped to a heater where it is vaporized under pressure, and the vapour so formed is mixed with the other overhead vapour stream, preferably in a venturi-type injector, to produce a vapour-blend of elevated temperature and pressure which is passed in heat-exchange with a stream of liquid or vapour to be fed to the still.  The process may be used in solvent refining, solvent dewaxing and solvent deasphalting, and also in the distillation of mineral oils, alcohols and essential oils. Feedstock is introduced through line 1 into colum 2 from which an overhead fraction is withdrawn by line 3.  The overhead vapour is divided into two streams, and one steram is condensed in heat-exchanger 13.  The condensate flows into tank 14 from which it is pumped to heater 16, where it is vaporized under the increased pressure.  The high-pressure vapours are passed to injector 17, and simultaneously draw into it the second stream of overhead vapour via line 18.  The blended vapours are passed through line 19 to heat-exchanger 11 where they condense, and effect the vaporization of liquid withdrawn from the base of the column into heat-exchanger 11 via line 8.  The reboiled fraction is returned to the column via line 9, the residual liquid being withdrawn as bottoms product via line 10.  The temperature of the condensate, withdrawn from heat-exchanger 11, is adjusted to the required reflux temperature in heat-exchanger 4; and part of the liquid is then introduced into the head of the column via line 6, while the remainder is withdrawn as product through line 7.
